I have the book. I bought it through abebooks from a bookseller in Warsaw who has helped me in the past. The main text is in Polish, but there are summaries in both French and English. The uniform prints are good, and some of the artillery material is very good, including some of the illustrations. The captions are in Polish, French, and English. It isn't a primary source volume, but it is useful and it covers a subject that is rarely covered in any depth. I'd recommend it, but to use it with some care. It's a first step in research, not a final product.
